"bin/make_dis festvox" should do everything. Into distribution of the
clunits voice you must include the following:

festvox/*.scm
festival/clunits/$FV_VOICENAME.catalogue
festival/trees/$FV_VOICENAME.tree
mcep/*.mcep
wav/*.wav

In festival/lib/siteinit.scm add a line (voice_your_voice_name)

You can check the code in speech_tools/sigpr, in particular the function

void sig2lpc(const EST_FVector &sig, EST_FVector &acf,
                EST_FVector &ref, EST_FVector &lpc)

If I understand correctly, this method is called Levinson-Durbin
Recursion as described on the page 294 in Spoken Language Processing.
